These 4 small clips were recorded in the same round. There are many more examples recorded here...
4 Headshots not registered. Playing DX11 with gtx 1080 and core i7 7700k 4.5 ghz with 16GB RAM. Fiber connection 30MB.
Since launch, my shots (with all guns) do not register and I get instantly killed all the time.
Drop my sniper accuracy from 42% in BF1 to 33% in BF5. I may be getting old, but as you can see in the video, this game is broken for many people.
